vacuum arc remelting furnace VAR is mainly used in universities and research institutes melting and making sample of sponge titanium and zirconium sponge active metals and refractory metal making raw materials, and then research and test their physical, chemical and mechanical properties to get new products. The main types of Vacuum arc melting furnace including VCF series vacuum consumable electrode arc furnace and VCF vacuum consumable electrode arc furnace.
vacuum arc VAR melting furnace for melting titanium molybdenum zirconium Product Description VAR is widely used to improve the cleanliness and refine the structure of standard air-melted or vacuum induction melted ingots, then called consumable electrodes.
Metalwerks Vacuum Arc Remelt (VAR) furnaces have an extensive range of capabilities. The crucible sizes range from ” diameter and up to 20” diameter. The furnace is setup to melt Fe, Ni, Co, Ti, and Zr alloys. This furnace is used to remelt VIM or ISM ingots into larger ingots for processing.
Remelting Variations Under Vacuum Apart from the remelting of a consumable electrode in a water-cooled copper crucible, State-of-the-art titanium vacuum arc skull melting furnaces are often equipped with turntable systems for centrifugal casting (up to 350 rpm). Casting weights of more than 1000 kg (2200 lb) are possible.
Yaran manufactures two types of vacuum arc (re)melting (VAR) furnaces – melting furnaces for specialty steels and super alloys and reactive furnaces for Titanium and other highly reactive metals. Both types are available in variety of sizes and production capacities.
Our titanium and titanium alloy ingots are melted twice using the VAR process. The procedure is known as the double consumable electrode vacuum arc remelting process. Double melting is considered necessary for all applications to ensure an acceptable degree of homogeneity in the resulting product.
Vacuum arc melting does not use refractory materials, and can smelt high-melting refractory metals such as tungsten, molybdenum, niobium, tantalum and highly active titanium and zirconium without
In this video, we melted smaples of Titanium, Molybdenum and Tantalum Nitride/Tantalum. Arc temprature easily exceeds the melting point of those metals and we only used a fraction of the furnace
Vacuum arc remelting (VAR) is a secondary melting process for production of metal ingots with elevated chemical and mechanical homogeneity for highly demanding applications. The VAR process has revolutionized the specialty traditional metallurgical techniques industry, and has made possible incredibly controlled materials used in the biomedical
Vacuum Arc Remelting Furnaces - Inductotherm Group. Vacuum Arc Remelting Furnaces VAR Furnaces for melting material that have already been melted and cast into electrodes that are near their full packing density.
